Self-observation means 1. observation (with an inner sense) of one's body or what is going on in one's body,2. observation of one's mind,3. observation of what one is doing.

I know only Augustinus' Confession, and David's psalms in Old Testament.I suppose there would be a lot of meditative books by Christians or ethical people writing about the mind, type 2, or what one is doing in everyday life, type 3.But I would rather like to read the type 1 (not that the type 2 and 3 is out of my concern).I guess there might not be type 1. in the field of religion or philosophy, but might be some in the field of medicine or alchemy.

The content would be on 1. how the body or the mind or the activity in life is before the eye of the observer, 2. the method of self-observation.3. bothAdd a note please to your recommendation about which of these types your book is.

I have an additional question to bedwere. Answer when you have time.Do you know of someone who treated the data from self-observation (especially of the body, rather than of the mind) in a creative way, creatively trying to understand them, and was always seeking to find some new things in the self ? I mean, for example, Marcus Aurelius' way of self-observation was, as far as I have read and heard, just adjusting the observed data to a standard (the Stoicism ? the common moral ?), and only observing what are already known (in Stoicism ?), and doesn't seem creative.

Thank you pster.As I tried looking over the pages of the book, in the LOOK INSIDE at Amazon page, this book did not seem to contain what I'm seeking for.Can you tell me where this book seems to fit me, and in what manner the self-observation appears in this book ?

I'm not sure. You seem interested in the body. I thought the book or texts it references might be up your alley. Just a thought. Sorry. I don't really know much about it. I own the book, but have never read it.
